Solfage
Here you can find the explanation for the Solfage application on iPhone. It's the same as the Do re mi fa app but in this app the bass clef was added.
1. Homepage
Choose here whether you want to to Train or to Quiz.
2. Train
After you chose train, you will have to determine if you want to train with the key of sol the key of fa (bass clef) or a mix of both. Once you made a choice you can start.
To train, tab the image area. You'll get a note. Tab again and you'll see the solution. Tab again and you'll get another note. That way it goes on and on. If you want to go back to the home page, click on menu. The range of the notes are 2 octaves.
3. Quiz
After you chose quiz, you will have to determine if you want to train with the key of sol the key of fa (bass clef) or a mix of both. Once you made a choice you can start.
To play the quiz, just tap the white square. a first cycle of 3 seconds starts running just as a warning. Then you get the first note that you have to guess in 3 seconds. If you are right, the button will become green. When you chose the wrong note, your button will turn red and the right one green. I called it quiz but this is more an infinite loop that keeps on going. So there's no score or ending. If you're tired of it, just press MENU to go back to the homepage.
